This month’s B2B will focus on the B2B July test for HVAC applications of an existing emergency space renovation and is based on chapter 8 (Health Care Facilities) in the 2015 ASHRAE Handbook — HVAC Applications, It is focused on the temporary HEPA filter systems installed within the construction space to maintain a negative pressure in this space.
Last month, I opened a discussion on how I have enjoyed integrated project delivery (IPD) and design-build (D-B) projects over the years and how I have been fortunate to learn from other team members as I shaped my “full team participation” (FTP) process.
This month’s Facility File will focus on the B2B June test for a heating application on a college campus, with a building program removing a dormitory heating system from the campus high-pressure steam system and replacing it with a high-efficiency condensing hot water boiler within the dormitory.
A new line of dedicated outside air systems (DOAS) from the YORK® brand of Johnson Controls includes a range of 100% outside air units and mixed air units. With heat pump operation and water source operation, as well as a hot water heat option, the new line of air systems delivers more combinations of heating and cooling. The systems also feature an internal energy recovery wheel that pre-conditions outside air and reduces heating and cooling loads by transferring energy between the exhaust airstreams.
Quantech™ has added QCC2 and QCC3 air-cooled, scroll-compressor condensing units for applications ranging from 15 to 160 tons to its portfolio of ready-to-ship products. The condensing units are designed for pairing with indoor air handlers using direct expansion (DX) evaporator coils. Quantech QDC condensers and QDCF fluid coolers are also available for air conditioning and refrigeration applications as high as 2,890 MBH.
Waste heat recovery innovation doesn’t make the news that often, so when it does, I have to wonder whether you, clever reader, can steer that innovation toward some creative advancements for the HVAC industry.
Over the years of designing and building HVAC infrastructure, I’ve been fortunate to be able to complete the projects via integrated project delivery (IPD) and design-build (D-B), in addition to design-bid-build (DBB) and construction management (CM).
